Loo's'E-LEAFBINER.

SPECIFICATION forming part of Ietters Eatent No.`729,979, dated-June 2,1903.

Applieation filed July 23, 1901.V Serial Nh. 679,384'- (No model.)

binder of this character adjustable in thicki ness to suit the bookcontents and so ar- -ranged that the book will 'always open flat andremain openunweighted, said binder bei ingparticularly adapted to theheavy class of work suggested.

My invention is illustrated in the preferred form in the accompanyingdrawings, in"

which- Figure l represents a broken inner view, partly insection, of theclosed end of the binder; and Fig. 2 a broken section takengas'-illustrated at line 2 of Fig. l.

In the preferred construction there are em-v ployed two separable coversections, two

clamping'bars, having hinged connection at their rear .or lower edgeswith the rear or'A binding edges of said cover-sections, extensiblebinding-posts connecting said clampingbars, extensible endclamping-posts detachably connected with the ends of said clamp-Aing-bars, anda spring-equipped follower re movably confined between saidclampingbars and serving to hold the booklcontents iirmly in placebefore the binder Ais filled'.

The preferred construction'is as follows: A'A4 represent cover-sections,the section A= being -provided at its hinged end with a tongue orextension a, which telescopes with a suitable pocket at the base orhinged end of the section A' in the manner shownin vmy existing" PatentNo. 606,434, June 28,1898; B B', hollow metallic clamping-barsrsecuredby hinges h' to the rear or binding portions of the sections A A; B2,telescopic bindingposts, the-large or tubular portions of which arecarried by the vbar B and the smaller portions of which are carried bythe bar B; C C, spring-equipped followers confined between the bars B B'and serving to hold the sheets c firmly against one of saidclamping-bars, and D detachable end binding posts connected with theends of the clamping-bars 'B B. rihe hinges b are firmly secured to thecover-section A A' by rivets b', which pass through perforations in'thehinged leaves h? and cverfsections A A', and to the rear side portionsof the clam ping-bars B B by brazing or 'otherwise securing thereto thehinged leaves b3. The followers C comprise bars or` members d, connectedby extensible posts d', about which are coiled springs d2, and connectedalso by a chain d3, which limits their separation.AsillustratedinFig.2,the members d are cut away atthe points d4 at theirextremities torpermit them to receive the posts B2. The end postsDcomprise, prefer-v ably, telescopically-connected members f ff. Themember f comprises a tubular portion f2, a hollow .bar-form partfparallel and adjacentthereto', an arm f4 at rghtangles t0 the`partsf2f3 and which serves to enter the h ollow bar B, anda iiatspringf5, secured to the part f4 at -its inner endand having near its outerend a perforation which receives a point f, with which the adjacentinner wall of the hollow bar B is provided. The part f comprisesa postf7, a parallel bar f5, an arm f9 at right angles thereto, and a springf1, provided with a'perforation receivingia stud f on theadjacentinner-wallof the clamping-bar B'. The parts f lfs'movetelescopically in the parts f2 f3 and are adj ustably connectedtherewith bya set-screwf12. AAny suitable means may be provided, ifdesired, to prevent the part f frombecomin g entirely separated from thepart f. Y

-In Fig. 2 I have shown the leaves c provided at their rear edges withnotches, recesses, or perforations" g for receiving the posts B2 andv attheir top and bottom edges with notches g'i'or receiving the members f8ofthe end posts D.; 1

lThe operation-will be readily understood from the foregoingdescription.The parts of vthe binder being assembled substantially as shown in Fig.l, but vwith the follower C removed, any desired number rof sheets maybe placed in the binder/the' thickness'of the book being regulated bythe screws fm. When the desired number of sheets are in place, assumingthe binder not to be filled, the follower C may be pressed into place toiirmly press the sheets against one of the clampingbars of the binder.When the binder is filled, the follower is of course no longer in use.As will be readily understood from the sectional portion of Fig. 1 theend binding-posts B may be readily removed from the clamping-bars, towhich they are secured,by pressing the springsjifo together by means ofthe thumb and finger to disengage ther perforations of said springs fromthe studsffu. This permits the leaves to be readily removed. When it isdesired to increase the capacity of the binder, the screws fm may beloosened and the binder-sections separated, the telescopic connection ofthe tongue ci. with one of the cover-sections permitting this action.

The leaves c may be of card board and have suitable recesses forreceivingr pictures when the binder is to be used as an album.

Changes in details of construction within the spirit ot' my inventionmay be made. Hence no limitation is to be understood from the foregoingdetailed description except as shall appear from the appended claims.

Vhat I claim as new, and desire to secure by Letters Patent, is-

l. In a binder of the character described, the combination of twosuitable cover-sections, two clamping-bars pivotally connected with therear edges thereof, and extensible end binding-posts detachablyconnected with 'the ends of both said clamping-bars.

:5. In a binder of the character described,

vthe combination of two suitable cover-sections, two clam ping-barshinged to said coversections, extensible intermediate bindingposts connected with said clam ping-bars, and extensible end binding-postsdetachably connected with both said clamping-bars.

3. In a binder of the character described, the combination of twosuitable cover-sec tions, two clamping-bars hinged thereto and havinghollow ends, and extensible bindingposts connected with said hollow endsand provided with inwardly-extending arms projecting into and detachablyconnected with said hollow ends.

4. In a binder of the character described, the combination of twosuitable cover-sections, two clamping-bars hinged thereto, andeXtensible end binding-posts detachably connected with saidclamping-bars and which comprise two telescoping 1nembers,and means forfirmly securingsaid telescoping members together in any desiredposition.

5. In a binder of the character described, the combination of twosuitable cover-sections, two clamping-bars hinged thereto, extensibleintermediate binding-posts connecting said clamping-bars, and extensibleend binding-posts detachably connected with the ends of both saidclamping-bars.

6. In a binder of the character described, the combination of twosuitable cover-sec tions, two clamping-bars connected therewith,extensible posts connecting said clamping-bars, and a spring-equippedf0llower,c0mprising two bars joined by extensible posts, springs tendingto separate said bars, and means forlimiting the separation of saidbars, said bars being provided with recesses for receiving aclamping-bar binding-post.
